Abstract
A fixing device includes a substrate, a first heat generator, a second heat generator with a length in a longitudinal direction of the substrate equal to a length of the first heat generator; and a third heat generator with a length shorter than the lengths of the first and second heat generators, a soaking member with a positioning portion in the longitudinal direction. In a short side direction of the substrate, the first heat generator is arranged at one end side, the second heat generator is arranged at the other end side, and the third heat generator is arranged between the first and second heat generators. The soaking member is arranged between the heater and a holder in a thickness direction. As seen in the short side direction, the positioning portion is positioned outside of an area corresponding to the third heat generator and inside of an area corresponding to the first heat generator.
